A single-crystal LiNi0.6Co0.2Mn0.2O2 is prepared by a hydrothermal method.
- •
A high discharge capacity of 183.7 mA h·g−1 at 0.2 C and good cycling stability.
- •
It yields an initial discharge capacity of 153.6 mA h·g−1 at 10 C-rate under 2.8 V–4.3 V.
- •
Superior electrochemical performance may be obtained attributed to the single-crystal structure.
